MIDDLESEX COUNTY — Two men and a woman, all from North Brunswick, face charges for robbing a string of convenience stores with paintball guns in that town as well as in East Brunswick, South Brunswick and Milltown.

The woman, 18-year-old Crystal Davis, the youngest of the three suspects, also was charged separately with the March 26 robbery of a taxi cab driver who was stabbed in the head, authorities said.

Police said Davis, Tyree Romero, 21, and Jeremy Barge, 27, who all lived together, are charged with robbery, unlawful possession of a weapon, and conspiracy to commit robbery for the hold-up at the Welsh Farms store on Hidden Lake Drive in North Brunswick last week.

However, in a search of the suspects' residence, investigators found proceeds from the robberies at a Hess station in East Brunswick, at a Quick Chek on Route 27 in South Brunswick and at the 7-Eleven store on Ryders Lane in Milltown, both last week, Capt. Roger Reinsen said .

Police got a break in the case when a North Brunswick apartment resident complained of people shooting paint balls.

All the robberies, in North Brunswick, East Brunswick, South Brunswick and Milltown occurred last Tuesday or early Wednesday last week, authorities said.

On Friday, North Brunswick police received a report of people shooting paint ball guns at the North Brunswick Manor Apartments off Route 1 near Livingston Avenue, Reinsen said.

Officers found Romero and Davis with the guns, and also found Davis had a knife and drug paraphernalia, Reinsen said.

Investigators questioned and charged the two suspects, then got a warrant to search their apartment, where they found Barge. Police also suspect the three alleged bandits were planning additional robberies, captain said.

He said all three suspects are being held today at the Middlesex County jail in North Brunswick.

South Brunswick police have also charged the three suspects with robbery and possession offenses.
